We return to Brazil this week where Cimento Itambé has inaugurated a new kiln at its plant in Balsa Nova, Parana. The US$92m investment has added 0.6Mt/yr of cement production capacity to the unit, bringing its total to 3Mt/yr. Notably, the new kiln is intended to support the use of alternative fuels (AF) such as biomass and industrial waste. Local press reports that the new kiln can operate with a 50% AF thermal substitution rate (TSR) and in tests it has reached as high as 67%.

Local market leader Votorantim Cimentos has also embarked on an upgrade programme linked to increasing co-processing rates. In May 2025 it said that it had received and begun installing a new cement mill, supplied from China, at its Salto de Pirapora plant near São Paulo. Earlier in August 2025 it revealed that it was spending US$60m on upgrades at its Nobres and Cuiabá plants in Mato Grosso. A new cement grinding mill is to be installed at the Nobres plant. This should increase the site’s cement production capacity to 1.2Mt/yr from 0.6Mt/yr. At Cuiabá the company is installing a tyre shredding unit via its Verdura subsidiary to support increased rates of co-processing of AF. Work on these projects is set to start in 2025 with completion scheduled by the end of 2026.

These schemes are part of the group’s larger US$920m upgrade investment plans across the country. Announced in early 2024, this is intended to increase competitiveness and co-processing capacity and reduce CO2 emissions. It will also add 3Mt/yr to the company’s production capacity. An investment of US$150m from the International Finance Corporation (IFC) in 2023 to Votorantim to support the uptake of AF is likely to have helped the decision to upgrade. The company currently has a target of a 50% TSR by 2030.

Of the other major producers, CSN is also aiming for a 50% TSR by 2030. It said in its 2024 sustainability report that all of its kilns were capable of processing AF. It also highlighted upgrade work at its Alhandra, Paraíba, plant in 2024 to handle, store and transport fuels, including biomass. InterCement reported some relatively high TSRs at individual plants in Brazil in 2023. For example, its Ijaci plant in Minas Gerais reportedly had a rate of 42%.

National Cement Industry Union (SNIC) data shows that the co-processing rate of AF reached 32% in 2023. The union says that this puts the sector ahead of its next target of 30% in the mid-2020s. The next one is to reach 35% by 2030. For reference, back in 2019 the country’s Cement Technology Roadmap reported that around 60% of cement kilns in the country were licensed by environmental agencies to co-process waste.

Looking at the domestic industry in general, SNIC reported growth in 2024 and the first seven months of 2025. Sales for the first seven months of the year grew by 4% year-on-year to 38.2Mt. This has been attributed to the real estate sector, boosted by the Minha Casa Minha Vida housing programme, and an expanding job market. Yet jitters remain, with fears of an economic slowdown in the second half of 2025 and uncertainty on how new US tariffs might affect the cement industry indirectly. Despite only exporting around 65,000t of cement in 2024 though, the association is wary of any indirect effects of tariffs.

It’s no surprise that cement plants in Brazil are prioritising AF usage. The market is buoyant and co-processing offers one of the cheapest routes to decarbonising cement production in the short-to-medium term. Increasing the use of AF can also potentially hedge against the cost of imported conventional fuels, such as coke, that are priced in US dollars. This is one example of SNIC’s concern over indirect effects on the cement industry from US tariffs via currency volatility. Expect AF rates to carry on rising.

The 18th Global CemFuels Conference & Exhibition on alternative fuels for cement and lime will take place on 17 - 18 September 2025 in Milan, Italy


Saudi Arabia: Najran Cement has elected Fahd Abdullah Al Rajhi as the chair of its directors for a four-year period. Majed Ali Hussain Musallam was also elected as vice chair.


Denmark: Christopher Ashworth has resigned as the president of FLSmidth Cement. A new president will be announced for the company after it has completed its divestment to Pacific Avenue from FLSmith. In the interim period Cori Petersen, the Executive Vice President of FLSmidth, will work as the acting president of FLSmidth Cement. Ashworth joined FLSmith Cement as its president in 2023. Previously he worked as the vice president and managing director of Eurotherm, a subsidiary of Schneider-Electric.


China: Anhui Conch’s revenues fell by 9% year-on-year to US$5.77bn in the first half of 2025 from US$6.37bn in the same period in 2025. Its net profit grew by 32% to US$587m from US$445m. Its net sales of cement and clinker remained stable at 127Mt. The group said that despite facing “insufficient demand, intensified competition and volatile market conditions” it managed to improve its efficiency, reduce operation costs and expand its market. Notable cement sector achievements during the reporting period included signing a deal to buy selected assets from West China Cement in China, acquiring Conch West Papua Cement in Indonesia and completing a 5000t/day production line at Phnom Penh in Cambodia.


Kenya: A group of four flour mill owners and associates has acquired Savannah Cement for US$29.4m, according to local press. The producer had been under administration for two years after it owed lenders KSB and Absa Bank debts of US$108m. The Competition Authority of Kenya approved the deal on 25 August 2025 without conditions, saying it posed no competition or public interest concerns.


Saudi Arabia: The National Center for Waste Management (MWAN) completed a five-month trial with Riyadh Cement on the use of iron slag in ordinary Portland cement, according to the Saudi Press Agency. The study used 1274t of slag and showed that adding 1 - 2% improved the cement’s properties. MWAN said that the results confirm the feasibility of using industrial byproducts to cut waste and reduce CO₂ emissions.


Thailand: Domestic cement sales are expected to decline by 5.5% year-on-year to 34.7Mt in 2025 due to a contraction in private construction, particularly new housing projects, according to local press. In the first quarter of 2025, sales rose by 9.6% to 8.8Mt. Government projects will continue to expand but at a slower pace than in 2024, which is reportedly insufficient to offset weaker private demand. Political uncertainty may delay the 2026 budget and new project bidding, which could impact demand for government construction projects from late 2025 into 2026.


China/US: A team led by Fengyin Du, then at Southeast University in Nanjing, developed a new cement formulation that reflects sunlight and emits heat more effectively than ordinary Portland cement, according to the New Scientist. The cement incorporates reflective ettringite crystals on its surface, which Du says “works like a mirror and a radiator, so it can reflect sunlight away and send heat out into the sky, so a building can stay cooler without any air conditioning or electricity.”

To make it, the researchers produce tiny pellets from limestone and gypsum, which are ground and mixed with water before being poured into a silicone mould covered in small holes. Ettringite crystals grow in slight depressions on the surface created by air bubbles, while an aluminium-rich gel allows infrared light to pass through, lowering heat retention.

Du said that tests at Purdue University, Indiana showed the cement’s surface was 5.4°C cooler than the air and 26°C cooler than conventional cement under the same conditions. The process is reportedly scalable and costs US$5/t less than ordinary Portland cement, as it can be produced at lower temperatures.


Norway: TotalEnergies, Equinor and Shell have announced that the first CO₂ volumes were transported by ship from Heidelberg Materials’ Brevik cement plant to Northern Lights’ Øygarden facilities. They were then injected 2600m under the seabed, 100km off the coast of western Norway. Phase one of the project has a storage capacity of 1.5Mt/yr. A second phase, approved in March 2025, will expand capacity to more than 5Mt/yr from 2028.

TotalEnergies’ senior vice president of carbon neutrality Arnaud Le Foll said “With the start of operations of Northern Lights, we are entering a new phase for the CCS industry in Europe. This industry now moves to reality, offering hard-to-abate sectors a credible and tangible way to reduce CO₂ emissions.”


Algeria: Biskria Ciment has exported 28,000t of white cement to the US from the port of Annaba aboard the M/V Anhui, according to the Annaba Port Company via L’Expression newspaper. The exports continue despite a 30% US customs duty on Algerian imports.

The company said it is maintaining shipments by leveraging the quality and price competitiveness of its cement.


India: Star Cement subsidiary Star Cement North East has been named preferred bidder for the Parewar (SN-IV) limestone block in Jaisalmer, Rajasthan. The 960-hectare block holds an estimated 271Mt of limestone. The company said the mining lease will strengthen its long-term raw material security once clearances and agreements are completed.

Star Cement operates 7.7Mt/yr of cement grinding capacity and 6.1Mt/yr of clinker capacity.


El Salvador: Data from the Central Reserve Bank (BCR) showed apparent cement consumption rose by 30% year-on-year in May 2025 to 4.8m 42.5kg bags, from 3.7m bags in May 2024, according to local press. The figure was the country’s highest monthly consumption in five years. Consumption from January to May 2025 reached 21.4m bags, up by 17% year-on-year from 18.4m bags in the same period of 2024.

From January to June 2025, imports of hydraulic cement totalled 0.3Mt, worth US$26m, up by 41% year-on-year from 0.21Mt in the same period of 2024. Guatemala was the leading supplier at US$12.7m, followed by Vietnam (US$6.6m), Japan (US$2.8m), Honduras (US$1.4m) and China (US$1.3m).


Canada: MV Tamarack arrived at the Port of Montreal on 22 August 2025, completing its maiden voyage and becoming the first newly built cement carrier to serve the Great Lakes in 20 years. The 12,500t vessel, owned by Eureka Shipping, a joint venture between CSL and SMT Shipping, was delivered on 23 July 2025 at Holland Shipyard in the Netherlands. The ship replaces two older vessels, offering the same capacity and reduced environmental impact, according to the company. MV Tamarack has a 10,700m³ cement hold, diesel-electric propulsion, shore-power compatibility, biofuel capability and energy-saving cargo systems.


Brazil: Cia. de Cimento Itambé has inaugurated a new kiln at its Balsa Nova plant in the Curitiba metropolitan region following a US$91.8m investment, according to the Curitiba government. Mayor Eduardo Pimentel and other members of the government were in attendance. The project reportedly increases clinker production capacity by 120% and adds 600,000t/yr of cement capacity, raising the plant’s total to 3Mt/yr.

The kiln will replace up to 50% of fossil fuels with renewable energy sources like biomass and industrial waste.


US: Shipments of Portland and blended cement, including imports, fell by 7.5% year-on-year to 8.91Mt in May 2025, according to the latest figures from the United States Geological Survey (USGS). Shipments for January to May 2025 totalled 37.9Mt, down by 6% from the same period in 2024. Texas, Missouri, California, Florida and Michigan accounted for 39% of production, while Texas, California, Florida, Ohio and Illinois received 40% of shipments.

Clinker production was 6.38Mt in May 2025 , compared with 6.46Mt in May 2024. For January to May 2025, clinker output dropped by 10% to 24.5Mt. Imports for the period declined by 5% year-on-year to 9.81Mt.


Colombia: Argos simultaneously loaded three cement ships for the first time at its Cartagena maritime terminal, moving over 31,000t of bulk cement. Platform 1 shipped 7000t to the Antilles and 3000t to the Caribbean, while Platform 2 loaded 21,000t for the US.

By the end of July 2025, Argos had shipped 570,000t of bulk cement on 44 vessels and 50,000t of bagged cement on 15 vessels.

Vice president of Argos Regional Colombia Carlos Horacio Yusty said “This milestone demonstrates the strength of our logistics network and the capacity of the terminal in Cartagena to respond to international markets. Having loaded three ships simultaneously sets a precedent in our operation and encourages us to continue growing in competitiveness.”

The Cartagena terminal has an installed capacity to handle 3.5Mt/yr of cement, clinker and raw materials.


Zimbabwe: China-based Shuntai Holdings is reportedly in a legal battle with Bryden Country School in Chegutu over the construction of a cement plant 497m from its boundary, according to local press.

The Board of Governors said that the company disclosed its plans in February 2025 to objections from the school and parents, with construction still continuing despite a High Court order halting construction. The Board said that there was no supporting documentation for the company to operate, as the area is zoned for education and also hosts a secondary school and university. Bryden said that it lodged multiple objections against Shuntai’s environmental and social impact assessment, which it claims failed to address key health and safety issues, yet the Environmental Management Agency (EMA) granted approval in April 2025. The school has since reportedly taken legal action against the regulator. A High Court judge ruled in July 2025 that Shuntai Holdings was in contempt of the stop-work order, but construction reportedly continues.

In July 2025, Shuntai administration manager Yan Bo confirmed the company has invested US$70m in the project, which is expected to produce 0.8Mt/yr of cement starting in 2026.


Zimbabwe: The Environmental Management Agency (EMA) has ordered WIH-Zim Cement, a joint venture between West International Holding and Labenmon Investments, to stop construction of its Magunje cement plant after inspectors found violations of Environmental Impact Assessment (EIA) conditions, including failure to compensate displaced households, according to Bulawayo 24 News. The EMA fined the company US$5000 and issued an enforcement order halting all activity until ‘EIA certificate conditions are adhered to.’

An inspection on 16 July 2025 revealed that construction continued despite High Court directives and community complaints. At least 20 households have reportedly lost farmland to a diversion road, while one homestead lies within the project boundary. Inspectors reported that WIH-Zim had already cleared 10 hectares of land and begun building staff quarters for 600 workers without meeting relocation requirements. The EMA also reportedly found that the company had failed to obtain a Communal Lands Occupation Certificate from Hurungwe Rural District Council. The EMA said “Continuous monitoring of the project is essential as this is a sensitive high-impact project,” warning that construction cannot resume until all affected families are compensated and relocated.

Local press reported in May 2025 that the cement plant was ‘progressing well,’ with the completion of site levelling and connection to the national power grid established and 60 local people already employed.


China: Data from the National Bureau of Statistics showed that cement production in July 2025 reached 146Mt, down by 6% year-on-year and the lowest July level since 2009, according to Bloomberg. Output from January to July 2025 was 958Mt, representing a 4.5% year-on-year decline. The drop was attributed to the ongoing real estate crisis, weak infrastructure activity, and weather disruptions from heatwaves and storms. Bloomberg said that further declines are likely as producers shrink capacity to better align with demand.


Iran: Domestic cement demand fell by 8% year-on-year to 4.69Mt in July 2025, according to the Iran Cement Association. Cement output dropped by 11% year-on-year to 4.71Mt, while clinker production rose by 23% year-on-year to 6.31Mt. Cement exports grew by 1.4% during the period to 0.5Mt, but clinker exports declined by 11% to 0.5Mt.

In the first seven months of 2025, cement consumption fell by 7.3% to 34.6Mt from 37.3Mt in 2024. Cement output declined by 3.7% year-on-year to 37.8Mt, while clinker production was stable at 43.0Mt. Cement exports rose by 4.6% year-on-year to 3.37Mt, but clinker exports dropped by 21% to 3.53Mt from 4.45Mt.

The association attributed the fall in demand to a sluggish real estate market and difficult economic conditions. The government’s limits on cement production to address power shortages has also impacted production levels.


India: UltraTech Cement will offload a 6.49% stake in India Cements through an open market sale, following approval by its committee of directors and officers. The producer acquired control of India Cements in July 2024. The company did not disclose the value of the planned sale.
